This is a story that appeared in an anime "a couple of science human, fell in love, so they try to prove the existence of love."
People who have little cooking experience, in many case, who are male in my observation, "hate" rather than "disgust" the term of
"small quantity" or "slightly"
For example, "Slightly salt", "Slightly sugar", "Slightly papper", etc.
Recently, taking this as a reverse hand, it seems that cookbooks with quantitative notation, "Ginger tube 5mm" have appeared.
-----
The word "slightly" is like, for example,
"Directory" for those who have never touched a personal computer,
or
"Wi-Fi" for people who have never touched a smartphone
In any case, "slightly" is definitely a term that is difficult to understand for beginners in cooking.
-----
The reason that the author of the recipe describes it as "slightly" is that they think
"The introduction of this seasoning dramatically changes the direction of the taste of the dish."
It means that they ask us to check the state of the dish before it is completed. In other words, "tasting during the cooking process" can be performed.
To begin with, cooking is performed by Agile development.
However, a beginner of cooking cannot taste the state of the cooking process, and estimate the taste of the final stage of cooking.
This is because beginners only recognize dishes as "final products".
"Cooking" is a black box until the dish is completed
This is what happens when performed in "Waterfall Development".
-----
I know well that the amount of salt and sugar (somewhat) determines the success of a dish (whether it can be eaten or not).
In particular, I know that "overdosing with salt" makes recovery difficult terribly".
However, my wife could recover my failed dish with another seasoning (although sometimes not be possible, of course).
In such a case, I cannot help but respect my wife, as a system engineer.
